1. Overview
Ossila's Potentiostat is low-cost and easy-to-use system for performing electrochemical
measurements, including linear sweep and cyclic voltammetry, open-circuit potential, and
controlled potential electrolysis.
Cyclic voltammetry is one of the most widely used electrochemical techniques, providing
important information about materials including:
•Reduction and oxidation potentials
•Reversibility of a reaction
•Electron transfer kinetics
•Energy levels of semiconducting polymers
The Potentiostat is capable of outputting potentials up 7.5 V, and measuring currents as low as 20
nA, allowing for a wide range of material characterisation. The easy-to-use PC software included
with the system allows anyone to perform the measurement.

9. Operation
9.1 Measurement Types
The Electrochemistry software can perform 3 different types of measurement. Each measurement
type can be selected using the tabs at the top of the window. The available measurement types
are:
1. Voltammetry
2. Open Circuit Potential
3. Electrolysis
Each measurement type requires several settings to be selected before it can be performed.
(I) Voltammetry
The Voltammetry tab performs linear sweep and cyclic voltammetry measurements.
(II) Open Circuit Potential
The Open Circuit Potential tab measures the resting potential between the working and reference
electrode over time.
(III) Electrolysis
The Electrolysis tab applies a constant potential whilst measuring the current over time.

9.2 Taking a Measurement
1. Add your appropriate electrolyte solution into the electrochemical cell.
2. Place the lid on the cell and insert the working, counter, and reference electrodes.
3. Use the cell connection cable to connect the Potentiostat to the electrodes, each connector
on the cable corresponds to a specific electrode:
I. The red connector goes to the working electrode.
II. The black connector goes to the counter electrode.
III. The blue connector goes to the reference electrode.
4. Start the Ossila Electrochemistry software. The window shown in Figure 9.1 will open.
5. Enter the appropriate settings for your experiment into the software (explained in more
detail in Section 9.3).
6. Click the ‘Measure’ button.
7. If ‘Save After Measurement’is turned on, the measurement data and settings will be saved
once the sweep has completed.
9.3 Software Settings and Controls
There are several settings in the software which must be entered before taking a measurement.
These are found on the panel to the left of the window as shown in Figure 9.1.
